目的 探查超声检测颈椎前路术后入路间隙血肿及局部水肿情况的可行性,探讨术后不适症状成因.方法 24例行颈椎前路手术患者,分别在术前24h、术后第1天、第5天行颈部超声,排查术后血肿,并留取图像,运用Image J软件分别测量矩形限定区组织面积,计算得出局部水肿面积,结合患者术后不适症状评分,进行统计学分析.结果 24例患者术后均未见明显血肿形成.术后第1天、第5天局部水肿面积分别为(1.73±0.64)cm2和(0.67±0.58)cm2,两者差异具有统计学意义(P＜0.05),声调低下、声音嘶哑、颈部肿胀感、吞咽困难4种症状在术后第5天评分较术后第1天显著降低(P＜0.05).结论 术后不适症状受围手术期多种因素影响,超声可以作为颈椎前路术后早期检测局部血肿及水肿情况的有效方式.“,”Objective To investigate the feasibility of ultrasonography in the detection of postoperative hematoma and edema in the clearance of anterior cervical surgery and to explore the potential related causes of postoperative complications.Methods This study enrolled 24 patients with 2-segment hybrid surgery.All patients underwent ultrasonography at 24 hours before the surgery, 1-day and 5-day post operation, respectively.Postoperative hematoma was screened, and Image J was used to evaluate a specified rectangular area of local soft tissue at the surgical incision plane.The area of local edema was calculated and the results were statistically analyzed in combination with the postoperative complications score.Results 24 patients underwent ultrasonography at the appointed time, and no postoperative hematoma occurred.The area of edema at 1-day and 5-day post operation were (1.73±0.64) cm2, (0.67±0.58) cm2, respectively.Compared with 1-day post operation, the score of low tone, hoarseness, dysphagia, and feeling of neck swelling were significantly decreased (P＜0.05) in the 5-day post operation.Conclusions Postoperative complications were influenced by various factors during the perioperative period, and ultrasonography could be an effective way to identify hematoma and edema in the early stage after the surgery.
